Lorpen T3 Heavy Trekker Over the Calf

Features our unique T3 construction with maximum cushioning for protection and warmth. The combination of Merino Wool and PrimaLoft Yarn results in faster drying and wicking than just Merino Wool while still maintaining a comfortable feel against the skin. Best suited for cold or damp weather hikes where moisture is an issue.

Primaloft Yarn is made up of ultra-fine polyester fibers which are finer than cashmere, resulting in a luxuriously soft feel while providing unparalleled moisture wicking. When hiking, climbing or doing any aerobic activity, your body works up a sweat and emits heat and perspiration, but when you suddenly sit idle, you can easily start to freeze with an insulation that absorbs water. Primaloft fibers wick moisture away from the skin and trap body heat.

This is a fantastic sock for hikers looking who need warmth, padding, and dryness.

Lorpen began as a small manufacturer of technical socks in the Basque region of Spain in the early 1980’s. Our founders were looking to make innovative and functional socks for walking and hiking enthusiasts. We are now a company with manufacturing facilities located on two continents and we sell our socks in more than 60 countries worldwide.

While we have experienced significant growth, our founders still manage the company with their original vision intact, “to produce the best technical socks for serious outdoor activities.”

It's not unusual for our designers to head out into the local mountains that surround our headquarters in the morning before returning to design socks in the afternoon. This is what makes Lorpen different. Our passion and commitment to excellence is a direct result of living and working in a natural environment.

Our vision also includes a commitment to preserve the environment in every aspect of business. This means that whenever possible we work with fibres that are created from sustainable and manageable resources. We also develop manufacturing processes that are sensitive to the environment and reduce the amount of post production waste at all levels.

All of this is accomplished while we continue to bring new products to the market that increase the users comfort and durability. We're driven by our passion to make the best socks in the world.
